Proposed Amendments to NH Drinking Water Rules (Amendments to Revised Total Coliform Rule)

Description:

The existing rules in subtitle Env-Dw implement the state’s Safe Drinking Water Act, RSA 485, and are intended to be equivalent to the federal program promulgated by EPA under the Federal Safe Drinking Water Act so that New Hampshire can retain primacy to regulate New Hampshire’s public drinking water systems (PWS). Certain portions of the existing rules reflect federal Revised Total Coliform Rule (RTCR) requirements, codified in 40 CFR 141 Subpart Y, and federal Consumer Confidence Report (CCR) requirements, codified in 40 CFR 141.154(d). The proposed amendments to the rules in Env-Dw 700 would (1) ensure equivalency with the federal RTCR requirements, (2) update the definition of “clean compliance history”, (3) revise existing requirements for reduced monitoring frequency, (4) require public notice of reporting violations, and (5) update cross-references. The proposed amendments to Env-Dw 811.21(c) would ensure equivalency with federal CCR requirements regarding lead by deleting outdated language, while the proposed amendment to Env-Dw 811.21(d) would update the cross-reference to Env Dw 811.21(c).
